SINAMICS S220 DC link cover, 100 mm frame
The 6SL5166-3AD00-0AA0 is a spare-part DC link cover intended for SINAMICS S220 line and motor modules in the 100 mm frame size — a service item, not a converter or active drive, so it lives in the accessories slice of the SINAMICS S220 bill of materials rather than the power-section order code list. Siemens classifies it as Group Code R220, Product Group X0HX, falling under the Ordering Data Overview family — the same ordering skeleton used for S220 accessories, which is how the part slots into a standard Siemens Drive Technology configuration.
Product class C — non-returnable, single-piece MOQ
The listing marks Product class C: products manufactured or produced to order, which cannot be reused, re-utilized, or returned against credit, and ships in a quantity unit of one piece per package — so a spare-part request is a clean single-unit line on the PO, but a wrongly ordered cover cannot be sent back for credit.
Compliance posture — RoHS, REACH, export control
Export-control markings read AL: N / ECCN: N, which means the cover is not on a controlled-goods list and does not trigger an export licence review when it leaves the EU/US — relevant for sites that rebuild drives outside the country of origin.
Lifecycle read and sourcing posture
Because the part is non-returnable product class C, the practical sourcing path is to quote it to order against the BOM line, confirm the 100 mm frame match against the SINAMICS S220 line/motor module being serviced, and let availability and pricing settle at RFQ time rather than treat it like a stocked consumable.
